NET INCOME PER COMMON SHARE [Abstract] |
Net Income per Common Share | NET INCOME PER COMMON SHARE Net income per common share is presented on both a basic and diluted basis. Diluted net income per common share assumes the exercise of stock options using the treasury stock method, and, for the years ended December 31, 2010 and December 31, 2009, the conversion of the Company’s formerly outstanding convertible preferred stock into common stock using the two-class method, but only if these items are dilutive. The following tables reconcile the numerator and denominator for both basic and diluted net income per common share:
